How GRID EATER uses it
GRID EATER uses PostgreSQL for operational state in selected heavy Hetzner workflows. That does not make it the universal canonical public business database: current architecture assigns canonical public business authority to D1 where documented.
Why this architecture mattersOperational workflow state and canonical public data do not need to live in the same engine.
